If I set DND on my Yealink T42 I see the DND logo on the phone's display and also in the Windows client I see Do Not Disturb. If I go back to available, both change alright. Now if I set DND on the Windows client I don't see DND on the IP-Phone. So I'm not aware of this DND status. The status remains DND (without notice) even after shutting down the Windows Client! Also I notice that when I set 'Switch status back after' to '1 Day', that it gets resetted again somehow to 'Never', when I look back.
